The power pin and the power plastic shell are integrated by means of injection molding, the ohm-type spring sheet is mounted on the printed circuit board, a slotted hole is arranged at a position of the printed circuit board under the ohm-type spring sheet, contact pins in different shapes and pin connection modes are selected according to standard appearances of pins in different countries, one end of each contact pin is connected into a circular concave hole of the corresponding pin in a plugged manner, or each contact pin and the corresponding pin are integrated, the other end of each contact pin is flexibly connected with the ohm-type spring sheet in a plugged manner after penetrating through the slotted hole of the printed circuit board, and the pin is clamped by two sides of the ohm-type spring sheet. The novel connection type power pin is simple in assembly, reliable in contact, labor-saving, material-saving, high in assembly efficiency and easy in disassembly and assembly.
Description
Technical field
This novel power supply adaptor and charger field of belonging to is specifically related to the connected mode of printed circuit board (PCB) and power pin.
Background technology
Middle low power power supply adaptor and charger are a kind ofly to get alternating current from commercial power socket; Through power pin alternating current is introduced power supply adaptor or the inner circuit board of charger; By the various circuit conversion of circuit board, export the device of needed voltage and current combining form again.At present, be in the middle low power power supply adaptor and charger of plastic cement at shell, the overwhelming majority adopts the traditional wire bonds printed circuit board (PCB) and the connected mode of power pin, and sub-fraction then adopts the spring leaf way of contact.Prior welding mode need be used lead-in wire and scolding tin, and artificial welding is wasted time and energy; Efficient is very low, and simultaneously, lead-in wire needs special process with the welding portion of power pin; To avoid since pin cross the heat conduction heat and scorch plastic shell; But such technology is prone to produce the mass defect of bag weldering and dry joint, and pass rate and production efficiency are produced in influence, and the use of a large amount of scolding tin in production scene can cause environmental pollution and electric energy loss.Have, the defective products in the production engineering is done over again again, or when needing rework operation because of other reasons, the dismounting of circuit board is very inconvenient.
Summary of the invention
The technical problem that the utility model will solve provides the novel connected mode of a kind of power pin and printed circuit board (PCB), and its assembling is simple, contact is reliable, save manual work and material, efficiency of assembling is high, and dismounting easily.
The power pin of this novel connected mode comprises a printed circuit board (PCB), power pin, ohm-type shell fragment and plastic shell, and said ohm-type shell fragment is installed on the said printed circuit board (PCB), and the printed circuit board (PCB) place under the ohm-type shell fragment is provided with a slotted eye.
Said power pin and power supply plastic shell are injected into one; Pin standard external form according to country variant; Select for use difform contact pin to be connected with pin or mode that contact pin and pin are integrally formed: when using contact pin with the pin connected mode, have one on the said power pin and justify shrinkage pool, an end plug-in of contact pin is connected in the round shrinkage pool; The part that contact pin inserts circular hole becomes the bow type; The elastic force of this bow type of leaning on can form reliable the contact with pin, and the slotted eye that the other end of contact pin passes printed circuit board (PCB) is connected with ohm-type shell fragment plug-in elasticity, and the both sides of ohm-type shell fragment clamp said pin; Select for use under the situation that contact pin and pin be integrally formed, the slotted eye that an end of contact pin passes printed circuit board (PCB) is connected with ohm-type shell fragment plug-in elasticity, and the both sides of ohm-type shell fragment clamp said pin.
Utilize the utility model, can reach following beneficial effect: changed the connected mode of traditional welding, cancellation lead-in wire, scolding tin and artificial welding utilize the power supply of this novel connected mode more reliable, assembling is simpler, production efficiency is also higher.
Below in conjunction with accompanying drawing and embodiment, the present invention is done further detailed description:
